If you are using Robarts for the first time here are some things I have learned over the years. Use pockets but prepare them. Cut off the ends and shorten the hinge post by 3/8". Anything past the set screw is just extra weight. Put the set screws into the pockets and carefully thread them so that they seat properly. Back them out just enough to allow the hinge to slip in and out and leave them in permanently. Find the aluminum tube that will fit over the set screw post and put a piece of it over the post after gluing the pocket in. I am attaching a picture. Wish it were less fuzzy.

One more, well maybe two more things. Buy extra pockets. The set screws are tiny and impossible to find, and you will lose two of them to the shop floor before it is over. A large magnet bar helps but they bounce. Don't glue the hinge in until you are 150-200% sure that they are alligned. You think a DuBro is hard to dig out, wait till you try a Roberts! Is it worth it - yes.
If you worry about the set screw pits looking bad, cover them with a square of Monokote if monokoted or draw a panel line around them. That is what I am going to do with the one in the pictures. I have these pots all over my planes for hatches. Real planes are covered with decals pointing to hatch access fasteners. Why not ours!
